GUTIERREZ, Dora Marina et al. Contenido de sustancias antinutricionales de malezas usadas como forraje. Rev. latinoam. quím [online]. 2010, vol.38, n.1, pp.58-67. ISSN 0370-5943.

The main antinutritional factors (tannins, saponins, and phytates) and haemolytic activity of 13 fodder weeds used as animal feed in rural areas of the state of Querétaro, Mexico, were studied. A wide variation was observed for phytates (0.47-4.48 g/100 g of dry plant material as phytic acid equivalent), tannins (0.08-5.1 g/100 g of dry plant material as tannic acid equivalent), and saponins (0.092-1.5 g/100 g of dry plant material as diosgenin equivalent). At the concentrations evaluated, Sanvitalia procumbens showed the highest haemolytic activity, though this value fell into the safe range. However, according to the results obtained, Desmodium mollicum and Amaranthus hybridus, that had high contents of tannins and phytates, may both be less accepted by animals, and affect their health.

Keywords : weeds; antinutritional factors; tannins; saponins; phytates.
